Kendamil Classic Ready to Feed Stage 1 is the liquid version of Kendamil's Classic first infant milk: the same whole milk approach, GOS and FOS prebiotics and algae-sourced DHA, already mixed, UHT-sterilised and sealed in 250ml (8.5 fl oz) bottles. You open a bottle, pour, and feed. There is no water to boil, no scoop to level and nothing to cool down at three in the morning. It is suitable from birth, and Kendamil labels it for use as the sole source of nutrition to 6 months or alongside solids from 6 to 12 months. Kendamil sells it in the UK in cases of 18; we sell it by the bottle, in bundles of 18, 36 and 72.
Kendamil Classic is Red Tractor assured rather than organic certified. If you want the organic version of this bottle, see Kendamil Organic Ready to Feed Stage 1, which comes in 200ml bottles. For the powder this bottle sits alongside, see Kendamil Classic Stage 1.
What Is Kendamil Classic Ready to Feed?
Ready to feed (RTF, also called ready-made or premade formula) is infant milk that has been prepared and sterilised at the factory rather than in your kitchen. Kendamil launched its first ready-to-feed bottles in the UK in October 2021 as a 70ml hospital and starter format; the 250ml bottle followed, and the 18-bottle case appeared on kendamil.com in late 2023. It was the first ready-to-feed infant milk sold in the UK made without palm oil or fish oil, and it has stayed that way: the fat comes from whole milk plus rapeseed and sunflower oil, and the DHA comes from algae.
The bottles are shelf-stable. Unopened, they keep at room temperature for their full 12-month shelf life, so a case can live in a cupboard, a car or a nappy bag. Once opened, anything you have not poured into a feeding bottle goes in the fridge and is used within 24 hours.
Who buys it? In our experience three groups: parents of newborns who want a bottle they can trust in the first fortnight before a sterilising routine has settled, families who travel or split care between two households, and parents who use powder during the day and keep a bottle for night feeds. It also solves the problem of feeding anywhere safe water is not a given.
Kendamil Ready to Feed vs Kendamil Classic Powder
This is the question we get most, so here is the straight answer: the bottle follows the same nutritional philosophy as the tin, but it is not the powder with water added. A shelf-stable liquid has to be formulated differently, and Kendamil's ingredient list for the bottle is shorter and in places different from the tin's.
| Per 100ml |
Ready to Feed (250ml bottle) |
Classic Stage 1 powder (800g tin) |
| Milk base | Whole milk, demineralised whey, whey permeate | Whole milk, demineralised whey, skimmed milk, alpha-lactalbumin whey concentrate |
| Vegetable oils | Rapeseed, sunflower | Sunflower, coconut, rapeseed |
| Prebiotic fibre | 0.68g (0.61g GOS + 0.07g FOS) | 0.27g (GOS and FOS) |
| DHA / ARA | 15mg / 15mg | 16.1mg / 8mg |
| Nucleotides | None | 2.9mg |
| Whey to casein | About 52:48 | About 60:40 |
| Iron / calcium / vitamin D | 0.70mg / 60mg / 1.5µg | 0.66mg / 44mg / 1.35µg |
| Energy | 64 kcal | 67 kcal |
| Sterile | Yes, UHT-treated and sealed | No, needs water at 70°C or hotter |
| Shelf life | 12 months unopened, 24 hours opened | 2 years unopened, 4 weeks opened |
| Preparation | Shake and pour | Boil, cool, measure, mix, cool again |
Both are vegetarian, both use lactose as the only carbohydrate, and neither contains palm oil, fish oil, soy, starch or maltodextrin. The bottle carries more prebiotic fibre and calcium; the tin has nucleotides and whey enriched with alpha-lactalbumin. Babies settled on the powder usually take the bottle without fuss, because the base is the same whole milk and lactose, but treat it as a change of product rather than a change of format if your baby is sensitive to switches.
Kendamil Classic Ready to Feed Stage 1 Ingredients
Water, whole milk, demineralised whey (milk), demineralised whey permeate (milk), vegetable oils (rapeseed, sunflower), galacto-oligosaccharides (milk), fructo-oligosaccharides, docosahexaenoic acid oil (algae oil), oil from Mortierella alpina, L-tryptophan, L-tyrosine, L-histidine, inositol, L-carnitine, choline chloride, taurine, minerals (sodium citrate, calcium citrate, calcium phosphate, potassium phosphate, sodium chloride, magnesium chloride, ferrous sulphate, zinc sulphate, copper sulphate, manganese sulphate, sodium selenite, potassium iodide, potassium hydroxide), vitamins (A, D3, B1, B2, niacin, pantothenic acid, B6, biotin, folic acid, B12, C, E, K1), emulsifier: sunflower lecithin, antioxidant: tocopherol-rich extract.
Allergens: contains milk. There is no soy, no fish oil, no palm oil, no added sugar, no corn syrup, no starch and no maltodextrin. The DHA is algae oil and the ARA is oil from the fungus Mortierella alpina, the standard vegetarian sources used across European formula, which is why Kendamil calls the recipe vegetarian-friendly.
What the Numbers Mean
- 64 kcal, 3.3g fat, 1.3g protein and 7g carbohydrate per 100ml, with the carbohydrate almost entirely lactose (6.8g). That is the same energy density as breast milk, give or take, and lower than most powders.
- 0.68g of prebiotic fibre per 100ml, from 0.61g of galacto-oligosaccharides and 0.07g of fructo-oligosaccharides. That is more than double what the Classic powder delivers per 100ml.
- 15mg DHA and 15mg ARA, matched one to one. The DHA level meets the EU requirement for infant formula (20-50mg per 100kcal) and the ARA is added at the same level rather than at the lower ratio used in the powder.
- 0.70mg iron, 60mg calcium, 43mg phosphorus and 1.5µg vitamin D, with the calcium to phosphorus ratio close to breast milk's.
- Taurine, L-carnitine, choline (24mg) and inositol, which are the usual conditionally essential extras in a first infant milk.

How to Use Kendamil Ready to Feed Bottles
- Wash your hands and sterilise the feeding bottle and teat as you normally would. The milk is sterile; the bottle you pour it into is not.
- Check the best-before date and shake the bottle well. Whole milk fat can settle on the shelf; a good shake brings it back.
- Pour the amount you need into the sterilised feeding bottle. A newborn feed uses well under half of a 250ml bottle.
- Serve at room temperature or warmed. If you warm it, stand the feeding bottle in warm water or use a bottle warmer, then test a drop on the inside of your wrist. Kendamil's own instruction is simply "if warmed, check temperature of feed". We do not recommend microwaving any infant milk; it heats unevenly.
- Refrigerate the rest. Cap the opened bottle, put it in the fridge and use it within 24 hours. Kendamil is explicit that it should not be kept longer.
- Throw away leftovers. Milk that has been in a feeding bottle should be used within two hours of being poured, or within one hour of your baby starting to feed, and never reused. Do not prepare a feed in advance and leave it out.
How Many Bottles Will You Need?
The feeding guide above uses Kendamil's suggested feed volumes and converts each age bracket into bottles per day and per month. A 250ml bottle holds two to three newborn feeds, so at one week a fully formula-fed baby uses about two and a half bottles a day; by four to five months it is closer to four. Over a month that is roughly 70 to 120 bottles, which is why our largest bundle is 72: about three weeks for a baby fed on Kendamil alone, or two to three months of night feeds for a family that mostly uses powder. Because an opened bottle keeps 24 hours in the fridge, very little is wasted even in the newborn weeks.
Where Kendamil Ready to Feed Is Made
Kendamil's powders are made at Kendal Nutricare's own factory in Kendal, on the edge of the Lake District. The ready-to-feed bottles are not: liquid formula needs UHT processing and aseptic filling, and Kendamil describes its ready-to-feed range as "lovingly made in Europe" for the company. It is a Kendamil recipe, sold under UK infant formula regulation, and Kendal Nutricare in Kendal is the manufacturer named on the pack. Like everything else we ship from Europe, the best-before date is printed in day/month/year order.
Is Kendamil Ready to Feed Available in the USA?
Not from Kendamil directly. Kendamil USA sells its Classic, Organic and Goat powders in 28.2oz cans and no liquid formula, and the UK bottles are not carried by US retailers. We import the UK product and ship it across the United States from our own stock, the same way we handle the powders. The UK and US Kendamil ranges are not identical, and our guide to Kendamil UK vs Kendamil US sets out the differences.
Moving From Stage 1 to Stage 2
Kendamil labels this first infant milk for use up to 12 months, so there is no requirement to switch at 6 months. If you do want a follow-on milk once solids are established, Kendamil Classic Ready to Feed Stage 2 comes in the same 250ml bottle with a little more iron (0.75mg per 100ml against 0.70mg) and 67 kcal per 100ml. Our guide on when to transition from Stage 1 to Stage 2 covers what to look for.
Kendamil Classic Ready to Feed Stage 1 FAQ – Everything Parents Want to Know
Is Kendamil Ready to Feed the same as the powder?
No. It follows the same whole milk, no palm oil, algae DHA approach, but it is a separate liquid recipe: rapeseed and sunflower oil rather than sunflower, coconut and rapeseed, more GOS and FOS per 100ml, no nucleotides, and a whey to casein split of about 52:48 rather than 60:40.
How long does an opened bottle of Kendamil Ready to Feed last?
Cap it, refrigerate it and use it within 24 hours. Milk that has been poured into a feeding bottle should be used within two hours, or within one hour of your baby starting the feed, and then discarded.
Does Kendamil Ready to Feed need to be refrigerated before opening?
No. Unopened bottles are shelf-stable and keep in a cool, dry cupboard for their full shelf life, which Kendamil puts at 12 months from production for the Classic first infant milk.
Can I warm Kendamil Ready to Feed?
Yes. Kendamil says to serve it at room temperature or warmed. Stand the feeding bottle in warm water or use a bottle warmer, shake, and test a drop on the inside of your wrist. We do not recommend the microwave for any infant milk because it heats unevenly.
Has Kendamil Ready to Feed been recalled?
There has been no safety recall of Kendamil Ready to Feed. In November 2025 some B&M stores in the UK removed 250ml bottles that had been left on shelf past their best-before date, which was a retailer date-compliance issue rather than a product problem. Our Kendamil recall page tracks every notice.
